I need help. How can I stop mourning?

[Max]

It is normal to be sad and grieve. With time, the feelings will not be as strong. You will always miss your grandmother, but with time, it will be more about remembering her for the great person she was and the times you had together. If you haven't lost many people in your life, that makes it harder too. Maybe you can do some things to keep yourself a bit busy too. For example, help your mother and other family members with getting ready for the funeral and the jobs that need doing with family all together, spend time with them talking about how you feel and remember that she became sick and maybe it was her time, as hard as that may seem. She would not want you to be so overcome. But, it will get better, really, it is part of life, you will go through it as well as the joyful times and new people coming into your family and life. See if you can get some decent sleep, that might help. Maybe write your grandmother a letter telling her what she meant to you, how much you loved her and why and why you are grateful to have had her in your life. She will always be with you in your heart. Good luck.
